Introduction

Tidy is a binding for the Tidy HTML clean and repair utility which allows you to not only clean and otherwise manipulate HTML documents, but also traverse the document tree.

Requirements

To use Tidy, you will need libtidy installed, available on the tidy homepage http://tidy.sourceforge.net/.

Installation

Tidy is currently available for PHP 4.3.x and PHP 5 as a PECL extension from http://pecl.php.net/package/tidy.

If PEAR is available on your *nix-like system you can use the pear installer to install the tidy extension, by the following command: pear -v install tidy.

You can always download the tar.gz package and install tidy by hand:

Example 1. tidy install by hand in PHP 4.3.x gunzip tidy-xxx.tgz tar -xvf tidy-xxx.tar cd tidy-xxx phpize ./configure && make && make install

Windows users can download the extension dll php_tidy.dll from http://snaps.php.net/win32/PECL_STABLE/.

In PHP 5 you need only to compile using the --with-tidy option.
